Abstract
Between 1979 and 1986, 29 pediatric patients underwent bone marrow transplantation at Texas Children's Hospital using routine reverse isolation. Laminar air flow rooms, prophylactic antibiotics, and gut sterilization were not utilized. The diagnoses included acute lymphocytic leukemia (ALL) (16 patients), acute nonlymphocytic leukemia (ANLL) (10 patients), and chronic myelogenous leulemia (CML) (three patients). All patients had fever during hospitalization. There were 11 episodes of bacteremia in seven patients giving a bacteremia rate of 37.9%. Moderate‐to‐severe (grade II–IV) acute graft‐versus‐host disease (GVHD) was seen in eight patients (27.6%). The incidence of infection and GVHD during the first 100 days post‐transplantation is comparable to published reports from centers utilizing rigid isolation and sterilization of the gut. It is suggested that bone marrow transplantation may be done using standard reverse isolation techniques without increasing the morbidity or mortality of the procedure.
